Now the core implements the work queue, remove it from the drivers,
and switch to using brightness_set_blocking op.

The constants used to specify ISINK ramp times for WM835x had the
wrong shifts so that the on times applied to the off ramp and vice
versa. The masks for the bitfields are correct.

The voltage and current regulators on the WM8350 AudioPlus PMIC can be
used in concert to provide a power efficient LED driver. This driver
implements support for this within the standard LED class.
Platform initialisation code should configure the LED hardware in the
init callback provided by the WM8350 core driver. The callback should
use wm8350_isink_set_flash(), wm8350_dcdc25_set_mode() and
wm8350_dcdc_set_slot() to configure the operating parameters of the
regulators for their hardware and then then use wm8350_register_led() to
instantiate the LED driver.
This driver was originally written by Liam Girdwood, though it has been
extensively modified since then.

Some WM8350 variants have fewer DCDCs and ISINKs. Identify these at
probe and refuse to use the absent DCDCs when running on these chips.

The WM8350 features six DCDC convertors (four buck and two boost), four
LDO voltage regulators and two constant current sinks. This driver adds
support for these through the regulator API.
This driver was written by Liam Girdwood with updates for submission
from Mark Brown.
